-f v claims. (c1. 'z2-i6) The invention -relates to concrete buildingsand more particularly to a novel building material in the form of slabs or sheets of reinforced concrete.

The object of theinvention is to provide rein- ;5- forced'concrete slabs, sheets orblocks by means ofwhichfa building may be cheaply, quicklyand easily constructed with spaced rows of slabs or sheets forming a hollow wall with an air space therein. A Y j Another object is to provide such slabs or sheets of concrete reinforced with expanded metal lath or the like projecting beyond the edges vof the slabs, j

j A further objectis to form a building of such A 1.5i slabs or sheets, the projectingedge portions of the expanded metal of adjacentY slabs overlapping andvforming a'reinforcement for theconcrete joints which are formed between the slabs. o

l A further object is to provide relatively narrow spacingwslabs or sheets adapted to be located transversely through the hollow wall `and having projecting edge portions of expended metallath or4 the likelextended into the joints between slabs j of the inner and outer tiers of the wall. Another object is to provide slabs-of angular shape for forming corner portionsY of the `walls of a building. 1 l j A further object is to provide slabs of T-shape which may be used either 4for reinforcing the hollowfwall orlfor starting a partition-wall.

AA stillfurther object is to provide a novel form of slabor block having an integral window frame formedthereon. Y f j "Themabove, together with other objects which will be apparent from Vthe drawing `or which may later be referred to, may be attained by constructing the invention in the manner illustratedin the accompanying drawing, in which Figure l is a plan sectional view of a portion of a wall constructed-in accordance with the-infvention; j A 1 Fig. 2, a vertical transverse sectional view through a portion of `the wall of abuilding constructed in accordanceiwiththe invention; l l Vliig..3,` a fragmentaryelevation of theA improved window frame construction; and l. l

Fig. 4, a fragmentary elevation ,of'one of the improved slabs orsheets. i" kSimilar `numerals `refer to similar, "parts throughout'the drawing. j

'ljheslabsforsheets indicated generally at IU v maybe'form'd of concrete or the like of a height substantially that of the ceiling and of a suitable width for convenient handling and are preferably about one inch thick.

For forming corners of a Vbuilding or wall, the

angular slabs I3 are lprovided and are constructed in the samemanner as the nat slabs IB having the'expanded metal lath or wire mesh il imbedded therein and projecting beyond `the side edges thereof. l

In constructing a building, a footer or sill It of cement or the like is formed and the wall is constructed by imbedding spaced walls of the slabs therein as indicated at I5. The adjacent side edges of the slabs are spaced apart sufficiently to permit the projecting edges I2 of the metal lath `or wire mesh to overlap as'shown in Fig. l and these joints are then lled with cement or the like to provide a continuous unbroken wall. Wooden spacing strips I6 may be provided betweenthe inner and outer tiers of the wall at the joints and may either remain in the wall or may be removed after the joints of the slabs have been cemented.

`If desired, narrow"slabs Ilia, formed in the same manner as the slabs Ill,`mayV be provided at the joints, the projecting edges of the metal lath or wire mesh thereof extending into the joints so as to form a rigid structure when the joints are filled with cement, the narrow transverselyy disposedA slabs Ill thus reinforcing the hollow wall at intervals.

For the purposeof further strengthening the wall,`T-shaped blocks or slabsY I'I may be provided at` intervals, these slabs being formed in the same manner as the slabs I0 and provided with a central rib I8 of a width substantially the distance between the inner and outer slabs of the hollow wall. Thisrib I8 is provided with a reinforcing sheet of metal lath` or wire mesh I9, the projecting edge of which extends Yinto the joint between the slabs Il] so as to form a solid rigid structure when this joint is filled with cement. 1 j' i. j j In` order to obviate the necessityof 'using wood or metal` window or door frames, reinforced concrete unitsZU maybe provided around each windowor door opening, having the integral ribs 2l formed thereon, producing an integral concretewindow or door frame.. These units, as shown in .Fig`.1,"may` be of channel-shape and providedV with expanded Mk metal lath or wire mesh reinforcing sheets 22 of similar shape imbedded therein, the edges of said reinforcing sheets projecting beyond the edges of the unit so as to overlap the projecting edges I2 from the slabs I0, whereby a reinforced concrete joint may be formed between the units 20 and the slabs. Inside and outside trims may be moulded on said units 2li.

In Fig. 3 is shown the manner in which a casement window sash 23 may be mounted within the Window frame thus formed. Hinge leaves 24 may be xed upon the sash in usual and ordinary manner and provided with elongated hinge pins 25 adapted to be received within the bushings 26 of lead or the like moulded within pre-formed sockets 21 in the upper and low units 20, or in such sockets themselves the sash being adapted to swing into closed position against the ribs 2| upon the units 20. Y

A concrete cap 28 is placed upon the upper edges of the slabs forming the wall for each story of the building and preferably has the depending rib 29 forming a spacer between the upper ends of the slabs In of the inner and outer walls. The floor joists 3G, or at the top of the building, beams for the roof, may have their ends imbedded in the cap 28. This cap may have a groove 3| near its outer edge to receive the lower ends of the slabs l D forming the outer wall of the next upper story, these slabs being preferably slightly higher than the slabs I for the inner wall of said upper story.

For the purpose of properly spacing the inner and outer slabs I of said upper story, a wooden plank or strip 32 may be mounted upon the floor joists 3S acting as a stop against which the slabs forming the inner wall may be butted.

The slabs may have smooth surfaces for both the inner and outer walls, which permits of their being painted, plastered, stuccoed Vor otherwise finished, or Yany desired finish such as a pebble dash, Spanish or antique plaster or the like may be moulded in the surfaces of the slabs so as to producey the desired nish without additional cost.

As shown in Fig. 3, the channel-shaped window and door frames may be reinforced at their corners by an integral diagonal rib 33 of concrete moulded in the frame and extending transversely across the inside of the channel.

Holes may be formed in the top corners and sides of the reinforced concrete Window units to receive wooden plugs or pins 34 and 35 respectively to provide for easily attaching curtain rods, shade rollers and tiebacks for curtains or drapes.

It will bey obvious that with the construction above described, a very strong integral wall is produced since the jointsv between slabs or units are formed of the same concrete material as the slabs or units themselves, thus producing a cohesion of the various slabs, units and window and door frames rather than an adhesion such as Where tiles, blocks, bricks or the like of clay or similar material are joined together by mortar or the like.

A building so constructed will be greatly reduced in weight and greatly increased in strength over the ordinary brick or frame building because of the ideal method of distribution of reinforcing material and concrete throughout the walls of the building..
